A Study of the Prediction Requirements in Real-Time
Control of Wave Energy Converters.
IEEE Transactions on Sustainable Energy, 3 (1).
It is widely acknowledged that real-time control of
wave energy converters (WECs) can benefit from prediction of
the excitation force. The prediction requirements (how far ahead
into the future do we need to predict?) and the achievable predictions
(how far ahead can we predict?) are quantified when unconstrained
reactive control is implemented. The fundamental properties
of the floating system that influence the length of the required
forecasting horizon, as well as the achievable prediction, are characterized.
The possibility of manipulating the control, based on
prior knowledge of the wave spectral distribution, is also proposed
for the reduction of the prediction requirements, such that they are
within the range of predictability offered by simple stochastic predictors.
The proposed methodology is validated on real wave data
and heaving buoys with different geometries.
